🌳 Segtree

Segtree is a plugin designed for the segmentation of individual trees from imagery. It isolates tree in ovelapping tree context.

Input: RGB images or preprocessed point clouds.

Output: Binary masks of segmentated tree.

How it works

The user provides as input a color image and, optionally, a trunk detector mask. With a single click, the plugin automatically places prompt points on the detected trunk labels. These prompts are then used by SAM2 HQ (Segment Anything Model v2, High Quality mode) to segment the tree foliage associated with each trunk.
